Application led January 31, 1916. Serial No. 75,216.

To all whom t may concern:

Be it known that I, EnMUNn HOFFMAN, a citizen of the United Brooklyn, inthe county of Kings and State of New York, have invented a new anduseful Tmprovement in Sifter-Tops for Talcum- Powder Cans and the like,of which the following is la specification.

vThis invention relates in general to sifter tops for powder .dispensingpackages and the like and has more particular reference to sifter topboxes provided for the packaging of talcum and face powder, although itwill be manifest that the inventionhas other and wider application;

A principal obJectof the invention is the structed and arranged that nopowder may leak out when the box is closed, and this without regard tothe amount of handling and jostling in shipping that the-package mayreceive. v

Talcum powder boxes arefrequently packed with many other articles ingrips and traveling bags where they maylrub against certain surroundingobjects and the` sifter top moved angularly so that the perforationscome in registration and der leaks out into the bag.

Allt is'an object of this inventionto pro' vide a construction wherethis will not occur. Furthermore, indenting of the tops of powder boxesconstructed prior to my invention has frequently permitted the powder toleak out, whether the perforations of the parts were in registration ornot. This also my present invention aims to overcome.

A still further object of the invention is the provision of such apowder box which will be readily operable, which will not diEer inappearance materially from those already in use and which may beeconomically constructed. y

Other objects and advantages ofthe invention will'be apparentfas it isbetter understood from the following description when considered inconnection with the aceompanying drawing illustrating a preferredembodiment thereof. c

Referring to the drawing?? l.

Figure 1 is a partial side view of a tal-cum powder box equipped withacover embodying my invention;

States, resi ding in fastening 14 in the top of the cover.

the pow- Forv the purpose of illustrating my invention I have shown onthe drawing a talcum l powder box comprised of a body l0 having a cover11 on the top of which is secured a neck 12 by seaming or otherwisesuitably its lower edge 13 in an opening The neck 12 is closed at itstop 15 to provide a stationary top, this top being perforated as isusual with apertures 16 arranged at intervals on a circumference aboutthe center of the neck.

Upon the outer face of the stationary cover or top 15 is/placed a disk17 which may be termed an intermediate closure, this disk be.

ing alsor provided with apertures 18 extend,`

lng through it, said apertures 18 being adapted to aline with theapertures 16 under certain predetermined conditions, as will be laterdescribed. This disk is held in place, in the embodimentoi the inventionshown on the drawing, by -a rivet 19 extending through it and throughthe stationary closure.

An outer rotatable sitter closure 20, much like that .ordinarilyemployed except 1n certain particulars, which will be described,

embraces the neck. The bottom edge 22 of this closure is bent in toengage the outer surface of the cylindrical part of the neck 12 beneatha number of projections 23 which hold the outer lclosure 2O in place.This closure is also provided -with perforations 24 adapted to alinewith the perforations 16r and 18.

vThe stationary top 15 1s depressed at 25 arcuately about the center ofmovement of the disk and outer closure 20, and in the depression 25 adepressed part26 of the disk 17' is disposed, these depressionsproviding coperating stops which limlt the movement of ,the disk withrespect to the statlonary closure. Similar coperating stops between thedisk andthe outer closure are' provided by cutting awayvthe outerclosure to.. provide an arcuate slot 27 and pressing thedisk .up `toprovide a projection28 extendlng lnto the slot. `Fig. 4t shows thearrangement of the all@ parts when the container` is closed, and it willbe noted that in this event the stop 26 is in the forward end of thedepression or stop 25 in the .direction of movement of the disk toclosed position, this movementin the iigrespectively in the stationarytop, the disk and in the outer rotatable closure are out ofregistration. When it is desired to open the disk, the outer rotatablemember or closure is grasped by the hand and turned in acounter-clockwise direction. The early part of this motion isunaccompanied by a motion of the disk, this motion bringing the stop 28to the rear end of the slot`27, considered in connection with thedirection of movement. When the stop 28 contacts with the rear end ofthe slot 27 the apertures in the disk and in the outer rotatable closureare in registration, but they are both out of registration with theapertures in the stationary top, as

-is seen in Fig. 5. Further movement of the outer rotatable closure isaccompanied by movement of the disk imparted to it by the movement ofthe outer closure. The two movable parts thus move together over thestationary part until the stop 28 engages the forward end of thedepression or sto 25 of the stationary cover, in which posit1on theapertures in the stationary cover come into registration with thealready alined apertures in the disk and in the movable cover. Thisarrangement is seen in Fig. 6. 1n closing the container the operation isreversed,

and this by turning the outer rotatable cover or closure in a clockwisedirection. First the apertures of the disk and outer closure move out ofregistration and later the apertures in the disk and stationary closureare moved from alinement, bringing the parts back to the position shownin Fig. 4. On the drawing the apertures in each part are spaced adistance equal to twice the operative length of the slot 27 ordepression 25 and when thus arranged the apertures 24 are over theapertures 16 when the parts are arranged in closed position, at whichtime the apertures 18 are located halfway circumferentially betweensuccessive apertures 24 and 16.

lt will be manifest that in thus providing a sealor disk member betweenthe cover and closure'the friction between. the parts is. increased byreason of the fact that two sets of friction surfaces must move overeach other to permit opening of the container, thereby reducing andalmost entirely obviating the chance of inadvertent opening of a talcumpowder box while in a hand-bag or grip. Should one of the parts becomeloose and easily movable with respect to the others, the box ,will stillbe closed by reason of the fact morsa? that such movement cannot bringthe .three sets of apertures into the necessary registration. Also if acontainer is dented in such number of operations necessary .in theconstruction of the package.

1t is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts. without departing from the spirit and scope ofthe invention or sacrificing any of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

I claim: l
